    "Two incompatible stress concepts exist. Observation check-ins use the categorical values low, moderate, high, and unknown; general/manual events use an optional integer intensity 0..3 or missing/unknown.",
    "The observation-check-in scale has no explicit zero and does not define low as either zero stress, mild stress, or merely the lowest reported category.",
    "The generic event UI permits intensity 0, but labels it only as \"0\"; unlike symptom capture, it does not define zero as \"none\" or \"documented zero\" for stress.",
    "Missingness is technically distinguishable: observation check-ins use unknown; capture entries use unknown before persistence; patient general events use null when omitted. However, these representations are not unified into one subjective-stress contract.",
    "The legacy event.stress path is presence-based rather than an intensity series. association_engine.event_days classifies every stress row as an event without reading intensity, so synthetic rows with intensity 0 and NULL both count as stress-event days.",
    "Observation-check-in stress is self-reported and day-keyed, but it is scoped to an active personal observation and cannot be captured as an independent longitudinal stress series.",
    "observation_engine.evaluate_observation converts only moderate and high check-ins into stress factors; low and unknown are omitted. That is an existing evaluative threshold, not a neutral rendering of all reported categories.",
    "The repository explicitly documents that no sufficiently supported subjective stress/well-being series exists and that stress must not be derived from HRV, pulse, or sleep.",
    "The requested label \"Anspannung / Stress – persönliche Einschätzung\" is compatible as presentation copy only after a canonical scale and source contract are approved; the current contracts do not establish that meaning.",
    "No interpolation can be guaranteed for stress because no dedicated stress series provider exists. Existing Explorer infrastructure supports explicit missingness, but stress currently appears only as events/check-in factors, not as a gap-preserving self-reported series."

    "Existing event.stress semantics discard intensity and count explicit zero as an event, making that path unsafe as a subjective intensity series.",
    "Existing observation evaluation suppresses low and promotes moderate/high to known factors; legacy association presets also evaluate event.stress against symptoms. These semantics conflict with the requested neutral, non-evaluative series.",
